Abstract: Objective To investigate the correlation between clinical features of AIDS with tuberculosis and CD4T lymphocyte count through retrospective analysis of the case of AIDS with tuberculosis. Methods the CD4T lymphocyte count of 95 cases AIDS with tuberculosis and 30 cases pure pulmonary tuberculosis were respectively detected and comparatively analyzed.. The correlation among PPD, MycoDot, TB typing and CD4T lymphocyte count in AIDS with tuberculosis cases were analyzed. Results The comparison of the level of CD4T lymphocyte count between AIDS with tuberculosis cases and pure pulmonary tuberculosis cases had statistical significance. There was correlation between CD4T lymphocyte count and the imaging show, PPD, MycoDot, positive rates of sputum smear and TB typing. Compared with CD4<100/mm³ and CD4>100/mm³, the imaging of patching consolidation shadows, multi-cavitates, mediastinum and (or) axillary lymphadenectasis and the test of PPD, MycoDot, positive rates of sputum smear had statistical significance, and there was an obvious difference in incidence of tuberculosis between Ⅱand Ⅴ, but the single-cavity, multiple nodules and pleural effusion had no statistical significance. Conclusion The incidence of AIDS with tuberculosis was high, specially among extrapulmonary tuberculosis and hematogenous dissemination tuberculosis. When CD4<100/mm³ the clinical manifestations were not typical. The radiology imaging manifestations were diversified and the positive rates of the tests of PPD, TB antibody and sputum smear were low.
